How to make a video from a PDF

People search "PDF to video" wanting one of two things, and it's worth knowing which before you start.

Sometimes the PDF is a slide deck someone exported, and you want those pages on screen with a voice over them. That's a slideshow job, and free tools handle it.

More often the PDF is a document: a report, a paper, a manual, lecture notes, a textbook chapter. Nobody wants to watch pages of a report scroll by. What you want is a video that explains what the document says. That's a writing job first, and it's where AI tools earn their keep.

Option 1: Screen record the PDF

Open the PDF, start a screen recorder (QuickTime or Cmd+Shift+5 on a Mac, the Snipping Tool or Xbox Game Bar on Windows, Loom or OBS anywhere), and talk through it while you scroll and zoom.

It works for a quick walkthrough: showing a colleague where the clause is in a contract, or going over a form with a client. It's free and takes as long as the talk does.

It's bad for anything people are meant to learn from. Dense pages at video resolution are hard to read, scrolling makes viewers seasick, and a long unscripted take wanders. If you go this way, zoom in on the part you're discussing, and plan what you'll say about each page before hitting record.

Option 2: Turn the pages into a slideshow

If the PDF is already slide-shaped, treat it as slides.

• Convert the pages to images. On a Mac, Preview can export each page as PNG or JPEG. On Windows, many free PDF tools do the same.
• Drop the images into a video editor (iMovie, Clipchamp, CapCut, or anything else you have), one page per clip.
• Record a voiceover, then stretch or trim each page to match what you're saying over it.

You can also insert PDF pages as pictures into PowerPoint or Keynote and use their video export, which handles recorded narration and per-slide timing for you. Our guides on PowerPoint and Keynote cover that export step.

This gives a clean result with your voice and full control. It's also the most hands-on route: you're the scriptwriter, the narrator and the editor. Budget an afternoon for a few minutes of finished video.

Option 3: Have an AI read the PDF and explain it

For text-heavy PDFs, the useful video doesn't show the pages. It takes what the document says, picks the important parts, explains them in plain spoken language, and shows pictures that help. Doing that by hand means reading the whole thing, writing a script, recording narration and making visuals. AI tools can do all of it.

Rekka is one of these. You give it a PDF and it makes a narrated, hand-drawn explainer video in a whiteboard, chalkboard or crayon style.

1. Open the chat at rekkaai.com/app.
2. Attach the PDF. Photos or scans of pages work too.
3. Send it. Add direction if it helps: "focus on section 3", "explain it for a first-year student", "skip the methods, cover the findings", or a language. With no message, the video covers the whole document.
4. The finished mp4 appears in the chat. Download it, or share it with a public link.

Rekka reads the pages one by one, including text, diagrams, tables and equations, and writes the script from them. Because the script comes from your pages, it uses the document's own terms, the ones a reader would see if they opened the PDF. The narration is an AI voice.

You can also ask questions about the PDF in the chat before making a video. That's free (no credits), and useful for checking it has understood a tricky section before you spend a credit.

There's more on the PDF to video page, and document to video covers the other formats Rekka reads: Word, PowerPoint, Keynote, Pages, OpenDocument, RTF, plain text, and spreadsheets from Excel, Numbers or CSV.

What to expect from an AI-made PDF video

A few honest limits, so the first one doesn't surprise you.

It's a summary. A one-credit video runs about 100 seconds. At around 150 words per minute of narration, that's roughly 250 words of script. A 30-page report can't fit in 250 words, so the video picks the main thread and leaves detail out. If you need a specific part covered properly, say so in your message.

On the free plan, the video is a single ~100-second chapter summarising the material, and new accounts get one free credit. Paid plans can make longer, multi-chapter videos that go through a document in more depth. Rekka shows you the length and the credit cost and asks you to confirm before it starts.

Up to 30 pages go in per message. For a longer PDF, split out the chapter or section you want, or point Rekka at it.

It doesn't reproduce the pages. The video is drawn scene by scene from the explanation, so your PDF's layout won't appear in it. If you need the pages themselves on screen, use Option 2.

Check facts the way you'd check a smart assistant's summary. The script is written by a model from your document. It's grounded in your pages, but read the narration for numbers and claims that matter before you send the video to anyone.

Tips for getting a better video from a PDF

Whatever route you take:

• Trim the PDF first. Cover pages, tables of contents, references and appendices rarely belong in a short video. Drop them, or tell the AI to skip them.
• Pick an audience. "Explain it to a new hire" and "explain it to the board" should produce different videos, and saying which one you want helps any tool, human or AI.
• One idea per scene. If you're scripting yourself, a scene that needs more than about 30 seconds of narration is usually two scenes.
• Keep it short. 60 to 120 seconds is a comfortable length for an explainer. A long document is better as a few short videos than one long one.
• Scanned PDFs are fine for AI tools that read the page, but a crooked, low-contrast scan is harder for anything to read. Rescan the worst pages if you can.

Which route to use

If you need to point at things on the page, screen record.

If the PDF is really a slide deck and you want your own voice over it, make a slideshow.

If the PDF is a document and you want people to understand it without reading it, have it explained. That's the case Rekka was built for.

Common questions

Is there a free way to convert a PDF to video?

Yes. Screen recording and the slideshow method both use free tools. Rekka gives new accounts one free credit, which makes one video of about 100 seconds.

Can AI turn a PDF into a video with narration?

Yes. Tools like Rekka read the PDF, write a script from it and narrate it with an AI voice. You can ask for the narration in another language.

Does it work with scanned PDFs?

Rekka reads what's on the page, and it accepts photos of pages as well as PDFs, so scans work. Clear, straight scans give better results.

What size video do I get?

Rekka makes an mp4 in landscape, square or portrait, so the same PDF can become a video for a course page or a vertical clip.
